SUSPENSION-mmm,

Patented Aug. 25, 1914.

Application iled April 1, 1918. Serial lo. 758,139.

To all whom it may concern:

Be it known that I, REUBEN B.ABnNJ'A- MiN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented new and useful Improvements inSuspension-Fittings, of which the following is a full, clear, concise,and exact description, reference being had to the accompanying drawing,forming a part of this specification. t In some conditions of electricservice, it is desirableto suspend a lamp socket or the like looselyfrom a cable or similar support, and when this is done it is usual toemploy a conduit secured to the socket and having at its upper enda'suspension fitting which is adapted to vbe secured to the lcable orother support. It is to `such suspension fitting that the presentinvention relates.

The principal object of the invention is to improve upon suspensionfittings of thi-s natu-re, to increase their safety and eiciency and tosimplify their construction.

It isa further important object of the invention to provide a suspensionfitting which will safeguard against abrasion of the outer coverings ofthe conductors, or other damage to the conductors, at the place wherethey enter the upper end of the conduits.

A suspension fitting constructed in accordance with my invention isshown, by way of example, in the accompanying d rawing and described inthe following specification. I wish it understood, however, that changesmay be made in the construction described and shown, without exceedingthe scope of my invention, as defined in the appended claims. t

In the drawing: Figure l is a side elevation of the suspension fitting;Fig. 2 is an4 inverted plan of the same; Fig. 3 is a cross section onthe line 3--3 of Fig. 2, looking in the direction of the arrows; andFig. 4 is a cross section on the line 4 4 of Fig. 2, 100ky conduit l2,to the lower end of which is se' cured a lamp socket or the like 13. Adiskshaped cover 14 ts over the disk 10, and is removably securedthereto by means of cap screws 15.. The cover 14 is formed with a.flange -15 which surrounds the upper edge of .the disk 1,-0, whereby thecover sheds off 'any moisture which may accumulate thereon 'and preventsaccess of such moisture to the interior of the fitting. The center partof the cover 14 i'sextended upwardly so as to form a rectangular hollowcasing 17, this casing being provided with an integral ring 18, forattaching the tting to the cable or other supporting member. An insulatiblock 19 is located in the casing portion '17 of the cover 14, and isprovided with two "downwardly-extending hollow bushings :20.

These bushings project through 'a pair of oppositely disposed slots 21,cut in the edge of the disk 10. The insulating block 19 is formed with alongitudinal channel 22 in its upper surface,` 'communicating `with thebushings 20, the channel terminating short of the ends of the block 19.At the center of the channel 22, theblock 19 is formed with an aperture23 of smaller diameter than the interior diameter o f the boss 11,whereby the conductors are prevented from engaging against the inside ofthe boss 11 or the top edge of the conduit screwed therein. Theconductors 25 are led int'o the fitting one through each of the bushings20. From thevbushings 20, the conductors pass through the channel 22tothe opening 23 through which theypass into the lnterior of 'theconduit. u

The ,suspensiontting described above is of simple construction and maybe produced at an exceedingly low cost. It may be wired with great easeand speed, and, is absolutely waterproof. The provision of the bushings20 and the making of the aperture 23 smallA enough to cover the innerend of the boss 11, prevents the4 coverings of the conductors frombecoming worn or abraded by contact with the metal parts of the fitting.

- Having thus fully described the nature "of my invention, what I claimas new and' desire to secure by Letters Patent is:

1. A suspension fitting comprising a supporting cover, aconduit-carrying member detachably connected with Isaid cover, and aninsulating member contained between said cover and said member, saidinsulating member having a. pair of conductor-receiving bushingsextending outwardly through said conduit-carrying member.

2.' A I' suspension ltt'ing "comprising a sup'- porting cover, aconduit-carrying member detachably connectedfwith said coverjfandy aninsulating member contained between said cover and said member, saidinsulating member havingva pair of conduit-receiving bushings extendingloutwardly through, said yconduit-carrying 'member' and being `formedwith a channel between said bushings, said channel having a centralopening for permitting passager ot the conductors tothe conduit. l

3, A suspension tting comprising a supporting cover, a plate detachablyconnected with said cover, said plate being formed with a pair ofopenings. and-having a hollow conduit-receiving boss,' and an insulatingmembery contained between said plate and said cover, said insulatingmember being' formed with openings for vreceiving conductorsregisteringl with theo enings oi said plateand being 'formed wit 1achannel between said openings, said channel having an openingregistering with said boss but of less diameter than the internaldiameter of.

said boss, forthe purposes set forth.

4f. A suspension fitting comprisinga supporting cover, a platedetachably connected with said cover, said plate having a hollowconduit-receiving boss, l and au insulating member contained` betweensaid plate and said cover, said insulating member having a pairofconductor-receiving bushings extending outwardly through said plate andbeing formed with a channel between said bushings, said channel havingan'opening registering with said boss but ci less diameter than theinternal diameter of said boss, for

the purposes set forth.

5. A suspension fitting comprlsing a diskshaped supporting'cover, saidcover having a rectangular enlargement forming a casing,

an elongated conductor-receiving insulating member contained insaidcasing, and a diskshaped conduit-supporting member detachably secured tosaid cover for retaining said insulating member in position.

6. A suspension tting comprising a flat supporting cover having a hollowenlargement at its center part, a conductor-receiving insulatingmembercontained in said enlargement, la conduit-supporting member or retainingsaid insulating member vin posinioeve "tin, and screws passing throughthe iiat portion lor' said cover and entering said conduit-supporting'member to .secure the latter porting member located within said angefor retaining said insulating member in position, and screws passingthrough the lat portion of said cover and entering saidconduit-supporting member to secure the latter in position. '1

9. A suspension tting comprising a supporting cover, a conduit-carryingmember detachably connected with said cover, said conduit-carryingmember provided with a. substantially central aperture for lead wires,and an insulating member contained between said cover and member, saidinsulating member having an aperture registering ywith the first saidaperture and having a'conduit therein leading from said second aperture.

l0. A suspension fitting comprising a sup porting cover, aconduit-carrying member detachably connected with said cover, saidconduit-carrying member provided with a substantiallyT central aperturefor lead wires,-

and an insulating member contained between said cover and member, saidinsulating member havingan aperture registering with but smaller thanthe first said aperture and having a conduit therein leading from saidsec-.

4 ond aperture.

In witness whereof, I havey hereunto subscribed my name in the presence'of two witnesses.
